Default Ktm 125 2009 rear brake sticking

     

Went riding on a enduro track yesterday was quite wet after a while all of a sudden my rear brake locked up then freed itself a hour later the same thing it kept happening! Last week it stopped working totally and I run out of fluid for it so I used clutch mineral fluid as a emergency not sure if this is what's causing it but the wheel is now turning but it's very stiff like it's rubbing! Anyone have any ideas ? Iv attached a link with a picture of the rear calliper

Time for new pads I'd say.

Before you replace them, pull the caliper apart and grease everything. Get any surface rust etc off with a bit of wet and dry sand paper, then steel wool before grease.
Look at the pin for instance. The brake pad needs to slide along that to re-align themselves.
Fresh fluid and a good bleed should see it right. There's plenty of how to vids on you tube.

I'm getting them tomorrow, strange why the brakes sticking on though, it had new pads like a month ago I only ride once maybe twice a week they've worn down so fast. I'm useless with calipers but I'll give it a go

Most likely beause they're not disengaging properly.

I find the Bendix, or Braking sintered pads last the longest for me.

i dont understand it cos the piston is moving freely in and out, i cant get pressure to build up or even fluid out the nipple think the master cylidner is goosed, its going in shop for master cylinder rebuild n hopefully back to normal reayd for weekend! whats best for keeping chain lubed up its a new chain and keeps drying out after one ride n a wash

As soon as you finish washing the bike. Spray the chain with a de-watering fluid. Or, CRC, WD-40, Inox etc.
